To all whom it may concern: 1

Be it known that I, JESSE FAIRLEY, a citizen of the United States. ofAmerica, residing at Sioux Falls, in the county of Minnehaha and Stateof South Dakota, have in vented certain new and useful Improvements inFastening Devices,of which the follow ing is a specification.

This invention relates to certain new and useful improvements infastening devices and pertains more particularly to devices which areemployed for securing the sections of forms used in concreteconstruction work.

' Ordinarily bolts are employed for securing the form sections together,but sameare objectionable due to the concrete entering and filling thethreads, resulting in difficulty in removlng the nuts andoftentimesstripping of the threads in removal.

The primary object of the present invention is therefore to provide afastening device which is not only devoid of threads and nuts, but whichalso can be more easily and quickly applied and removed in assembly andseparation of the form sections, and which at the same time holds thesections firmly and securely in assembled relation.

The invention still further aims to provide a fastening which can beeconomically produced and which effects a saving of time in beingapplied and removed.

Still further and other objects will be later set forth and manifestedin the course of the following description.

In the drawings:

Figure l, is a side elevation showing the invention applied in position;

Figure 2, is a top plan view of Figure 1;

Figure 3, is a section on line 8-3 of Figure 1, and

Figure 4, is a detail perspective view of the fastener.

While the invention is especially devised for and illustrated inconnection with concrete forms, it will be apparent that same can beused equally as well in connection with any elements susceptible ofconnection, and accordingly the angle-irons 1 and 2, with their webs 3and 4 abutting, are illustrated by way of example of one use of theinvention.

The invention embodies preferably a wire member having a bod 5 andlaterally bent ends 6 and 7, the who e constituting a somewhat U-shapedstructure. The end 6 has its free extremity pointed at 8, while the end7 is of hooked or J-shapedformation'as dei picted at 9. The material ofwhich the fastener is formed is possessed'of spring properties,-the; end6 normally having a tendency to lie outwardly at an incline as shown inFigure 4:. v '1' lnoperation, the abutting webs 3 and iars equipped withregistering openings '10 to re.- ceive the ends 6, a pair .of fastenersbeing employed and located in relatively close relation, the ends 6extending in opposite directions. As shown indotted lines to the leftof'Figure 1, the end 6 is first inserted thro'ughthe openingslO-and thebody and end '7 then moved downwardly to vcause the hooked end 9 tofirmly embrace and clamp the webs 3 and 4: in tight abutting relation,as shown in Figure 3, for whichv purpose the end 9 has a tight or closefrictional fit with the webs 3 and t. When the devices are in operativeposition as illustrated in Figure 1, the bodies 5 occupy an inclineddisposition with relation to the longitudinal axes of the angle-irons orother members to be connected and due to the spring action of the end 6,it will be seen that the end 9 and its hook 7 will be constantly urgedin a direction away from end 6, or held under tension, and since thebody 5 occupies an inclined position, the hook 9 will likewise be heldagainst the outer or free longitudinal edges of the webs 3 and 4.

The end 6 forms a pivot about which the clamping end 9 swings inapplying the latter in position.

What is claimed is 1. In a fastener for abutting elements havingregistering perforations, an approximately U-shaped spring wire memberhaving one end disposed at an incline and pointed and formed to bereceived in the perforations, and a hook-like part on the other endformed to embrace and frictionally engage opposite faces of the elementsso as to clamp the lattertogether, the body of the member bein at anincline to the longitudinal axes of the elements when in operativeposition.

2. In a fastener for abutting elements having registering perforations,a spring wire member having one end formed to engage through theperforations and having means on its opposite end to be forced over.

and frictionally engage and clamp the members together.
